Due to signalling staff illness there are no trains between Cardiff and Swansea from (24/4/25) 23:00 to 07:00 (25/4/25).
I am quite surprised that a mainline railway can just shut down completely at such short notice; where is the resilience? Is this why the railway is being used more for leisure these days as those travelling to/from school or work can't rely on it.
GWR▸ are apparently trying to source road transport.
It looks like they found a signaller - there are three trains out there at the moment at 05:00 - an empty passenger train, a freight train of some sort, and the first Swansea to London service passing through Briton Ferry
